Grief..

Ambiguous loss can be invisible to onlookers and may therefore go unacknowledged, leading to isolation and "frozen grief." 

It is important to acknowledge the gravity and costs of the loss in some way. Talk to a trusted loved one or a mental health practitioner.

The only person that truly understands the magnitude of your loss is you. Research explains that being compassionate with yourself and remaining mindful of your triggers can save you a great deal of heartache.

Research explains that channeling your negative emotions toward a cause—like rehabilitation efforts or dementia awareness—can help you leave your grief behind and create a sense of purpose from the loss. 

Just a thought.
